for lazy loading.

Overview

Two features: Images API (upload/store with variants) and Image Transformations (resize any image via URL or Workers).

Quick Start

1. Enable: Dashboard → Images → Get Account ID + API token (Cloudflare Images: Edit permission)

2. Upload:

bash

curl -X POST https://api.cloudflare.com/client/v4/accounts/<ACCOUNT_ID>/images/v1 \
  -H 'Authorization: Bearer <API_TOKEN>' \
  -H 'Content-Type: multipart/form-data' \
  -F 'file=@./image.jpg'

3. Serve:

https://imagedelivery.net/<ACCOUNT_HASH>/<IMAGE_ID>/public

4. Transform (optional): Dashboard → Images → Transformations → Enable for zone

html

<img src="/cdn-cgi/image/width=800,quality=85/uploads/photo.jpg" />

Upload Methods

1. File Upload: POST to

/images/v1

with

file

(multipart/form-data), optional

id

requireSignedURLs

metadata

2. Upload via URL: POST with

url=https://example.com/image.jpg

(supports HTTP basic auth)

3. Direct Creator Upload (one-time URLs, no API key exposure):

Backend: POST to

/images/v2/direct_upload

→ returns

uploadURL

Frontend: POST file to

uploadURL

with FormData

CRITICAL CORS FIX:

✅ Use
```
multipart/form-data
```
(let browser set header)
✅ Name field
```
file
```
(NOT
```
image
```
)
✅ Call
```
/direct_upload
```
from backend only
❌ Don't set
```
Content-Type: application/json
```
❌ Don't call
```
/direct_upload
```
from browser

Image Transformations

URL:

/cdn-cgi/image/<OPTIONS>/<SOURCE>

Sizing:
```
width=800,height=600,fit=cover
```
Quality:
```
quality=85
```
(1-100)
Format:
```
format=auto
```
(WebP/AVIF auto-detection)
Cropping:
```
gravity=auto
```
(smart crop), gravity=face
(AI face detection, Aug 2025 GA),
```
gravity=center
```
, zoom=0.5
(0-1 range, face crop tightness)
Effects:
```
blur=10,sharpen=3,brightness=1.2
```
Fit:
```
scale-down
```
,
```
contain
```
,
```
cover
```
,
```
crop
```
,
```
pad
```

Workers: Use

cf.image

object in fetch

typescript

fetch(imageURL, {
  cf: {
    image: { width: 800, quality: 85, format: 'auto', gravity: 'face', zoom: 0.8 }
  }
});

Variants

Named Variants (up to 100): Predefined transformations (e.g.,

avatar

thumbnail

)

Create: POST to
```
/images/v1/variants
```
with
```
id
```
,
```
options
```
Use:
```
imagedelivery.net/<HASH>/<ID>/avatar
```
Works with signed URLs

Flexible Variants: Dynamic params in URL (

w=400,sharpen=3

)

Enable: PATCH

/images/v1/config

with

{"flexible_variants": true}

❌ Cannot use with signed URLs (use named variants instead)

Signed URLs

Generate HMAC-SHA256 tokens for private images (URL format:

?exp=<TIMESTAMP>&sig=<HMAC>

Algorithm:

HMAC-SHA256(signingKey, imageId + variant + expiry)

→ hex signature

See:

templates/signed-urls-generation.ts

for Workers implementation

Critical Rules

Always Do

✅ Use

multipart/form-data

for Direct Creator Upload ✅ Name the file field

file

(not

image

or other names) ✅ Call

/direct_upload

API from backend only (NOT browser) ✅ Use HTTPS URLs for transformations (HTTP not supported) ✅ URL-encode special characters in image paths ✅ Enable transformations on zone before using

/cdn-cgi/image/

✅ Use named variants for private images (signed URLs) ✅ Check

Cf-Resized

header for transformation errors ✅ Set

format=auto

for automatic WebP/AVIF conversion ✅ Use

fit=scale-down

to prevent unwanted enlargement

Never Do

❌ Use

application/json

Content-Type for file uploads ❌ Call

/direct_upload

from browser (CORS will fail) ❌ Use flexible variants with

requireSignedURLs=true

❌ Resize SVG files (they're inherently scalable) ❌ Use HTTP URLs for transformations (HTTPS only) ❌ Put spaces or unescaped Unicode in URLs ❌ Transform the same image multiple times in Workers (causes 9403 loop) ❌ Exceed 100 megapixels image size ❌ Use

/cdn-cgi/image/

endpoint in Workers (use

cf.image

instead) ❌ Forget to enable transformations on zone before use

Known Issues Prevention

This skill prevents 16 documented issues.

Issue #1: Direct Creator Upload CORS Error

Error:

Access to XMLHttpRequest blocked by CORS policy: Request header field content-type is not allowed

Source: Cloudflare Community #345739, #368114

Why It Happens: Server CORS settings only allow

multipart/form-data

for Content-Type header

Prevention:

javascript

// ✅ CORRECT
const formData = new FormData();
formData.append('file', fileInput.files[0]);
await fetch(uploadURL, {
  method: 'POST',
  body: formData // Browser sets multipart/form-data automatically
});

// ❌ WRONG
await fetch(uploadURL, {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' }, // CORS error
  body: JSON.stringify({ file: base64Image })
});

Issue #2: Error 5408 - Upload Timeout

Error:

Error 5408

after ~15 seconds of upload

Source: Cloudflare Community #571336

Why It Happens: Cloudflare has 30-second request timeout; slow uploads or large files exceed limit

Prevention:

Compress images before upload (client-side with Canvas API)
Use reasonable file size limits (e.g., max 10MB)
Show upload progress to user
Handle timeout errors gracefully

javascript

const MAX_FILE_SIZE = 10 * 1024 * 1024; // 10MB

if (file.size > MAX_FILE_SIZE) {
  alert('File too large. Please select an image under 10MB.');
  return;
}

Issue #3: Error 400 - Invalid File Parameter

Error:

400 Bad Request

with unhelpful error message

Source: Cloudflare Community #487629

Why It Happens: File field must be named

file

(not

image

photo

, etc.)

Prevention:

javascript

// ✅ CORRECT
formData.append('file', imageFile);

// ❌ WRONG
formData.append('image', imageFile); // 400 error
formData.append('photo', imageFile); // 400 error

Issue #4: CORS Preflight Failures

Error: Preflight OPTIONS request blocked

Source: Cloudflare Community #306805

Why It Happens: Calling

/direct_upload

API directly from browser (should be backend-only)

Prevention:

ARCHITECTURE:
Browser → Backend API → POST /direct_upload → Returns uploadURL → Browser uploads to uploadURL

Never expose API token to browser. Generate upload URL on backend, return to frontend.

Issue #5: Error 9401 - Invalid Arguments

Error:

Cf-Resized: err=9401

- Required cf.image options missing or invalid

Source: Cloudflare Images Docs - Troubleshooting

Why It Happens: Missing required transformation parameters or invalid values

Prevention:

typescript

// ✅ CORRECT
fetch(imageURL, {
  cf: {
    image: {
      width: 800,
      quality: 85,
      format: 'auto'
    }
  }
});

// ❌ WRONG
fetch(imageURL, {
  cf: {
    image: {
      width: 'large', // Must be number
      quality: 150 // Max 100
    }
  }
});

Issue #6: Error 9402 - Image Too Large

Error:

Cf-Resized: err=9402

- Image too large or connection interrupted

Source: Cloudflare Images Docs - Troubleshooting

Why It Happens: Image exceeds maximum area (100 megapixels) or download fails

Prevention:

Validate image dimensions before transforming
Use reasonable source images (max 10000x10000px)
Handle network errors gracefully

Issue #7: Error 9403 - Request Loop

Error:

Cf-Resized: err=9403

- Worker fetching its own URL or already-resized image

Source: Cloudflare Images Docs - Troubleshooting

Why It Happens: Transformation applied to already-transformed image, or Worker fetches itself

Prevention:

typescript

// ✅ CORRECT
if (url.pathname.startsWith('/images/')) {
  const originalPath = url.pathname.replace('/images/', '');
  const originURL = `https://storage.example.com/${originalPath}`;
  return fetch(originURL, { cf: { image: { width: 800 } } });
}

// ❌ WRONG
if (url.pathname.startsWith('/images/')) {
  // Fetches worker's own URL, causes loop
  return fetch(request, { cf: { image: { width: 800 } } });
}

Issue #8: Error 9406/9419 - Invalid URL Format

Error:

Cf-Resized: err=9406

err=9419

- Non-HTTPS URL or URL has spaces/unescaped Unicode

Source: Cloudflare Images Docs - Troubleshooting

Why It Happens: Image URL uses HTTP (not HTTPS) or contains invalid characters

Prevention:

typescript

// ✅ CORRECT
const imageURL = "https://example.com/images/photo%20name.jpg";

// ❌ WRONG
const imageURL = "http://example.com/images/photo.jpg"; // HTTP not allowed
const imageURL = "https://example.com/images/photo name.jpg"; // Space not encoded

Always use

encodeURIComponent()

for URL paths:

typescript

const filename = "photo name.jpg";
const imageURL = `https://example.com/images/${encodeURIComponent(filename)}`;

Issue #9: Error 9412 - Non-Image Response

Error:

Cf-Resized: err=9412

- Origin returned HTML instead of image

Source: Cloudflare Images Docs - Troubleshooting

Why It Happens: Origin server returns 404 page or error page (HTML) instead of image

Prevention:

typescript

// Verify URL before transforming
const originResponse = await fetch(imageURL, { method: 'HEAD' });
const contentType = originResponse.headers.get('content-type');

if (!contentType?.startsWith('image/')) {
  return new Response('Not an image', { status: 400 });
}

return fetch(imageURL, { cf: { image: { width: 800 } } });

Issue #10: Error 9413 - Max Image Area Exceeded

Error:

Cf-Resized: err=9413

- Image exceeds 100 megapixels

Source: Cloudflare Images Docs - Troubleshooting

Why It Happens: Source image dimensions exceed 100 megapixels (e.g., 10000x10000px)

Prevention:

Validate image dimensions before upload
Pre-process oversized images
Reject images above threshold

typescript

const MAX_MEGAPIXELS = 100;

if (width * height > MAX_MEGAPIXELS * 1_000_000) {
  return new Response('Image too large', { status: 413 });
}

Issue #11: Flexible Variants + Signed URLs Incompatibility

Error: Flexible variants don't work with private images

Source: Cloudflare Images Docs - Enable flexible variants

Why It Happens: Flexible variants cannot be used with

requireSignedURLs=true

Prevention:

typescript

// ✅ CORRECT - Use named variants for private images
await uploadImage({
  file: imageFile,
  requireSignedURLs: true // Use named variants: /public, /avatar, etc.
});

// ❌ WRONG - Flexible variants don't support signed URLs
// Cannot use: /w=400,sharpen=3 with requireSignedURLs=true

Issue #12: SVG Resizing Limitation

Error: SVG files don't resize via transformations

Source: Cloudflare Images Docs - SVG files

Why It Happens: SVG is inherently scalable (vector format), resizing not applicable

Prevention:

typescript

// SVGs can be served but not resized
// Use any variant name as placeholder
// https://imagedelivery.net/<HASH>/<SVG_ID>/public

// SVG will be served at original size regardless of variant settings

Issue #13: EXIF Metadata Stripped by Format

Error: GPS data, camera settings removed from uploaded images

Source: Cloudflare Images Docs - Transform via URL

Why It Happens: Default behavior strips all metadata except copyright. CRITICAL: WebP and PNG output formats ALWAYS discard metadata regardless of settings - only JPEG supports metadata preservation.

Prevention:

typescript

// ✅ CORRECT - JPEG preserves metadata
fetch(imageURL, {
  cf: {
    image: {
      width: 800,
      format: 'jpeg', // or 'auto' (may become jpeg)
      metadata: 'keep' // Preserves most EXIF including GPS
    }
  }
});

// ❌ WRONG - WebP/PNG ignore metadata setting
fetch(imageURL, {
  cf: {
    image: {
      format: 'webp',
      metadata: 'keep' // NO EFFECT - always stripped for WebP/PNG
    }
  }
});

Metadata Options (JPEG only):

```
none
```
: Strip all metadata
```
copyright
```
: Keep only copyright tag (default for JPEG)
```
keep
```
: Preserve most EXIF metadata including GPS

Format Support:

✅ JPEG: All metadata options work
❌ WebP: Always strips metadata (acts as
```
none
```
)
❌ PNG: Always strips metadata (acts as
```
none
```
)

Issue #14: AVIF Resolution Limit Ambiguity

Error: Large AVIF transformations fail or degrade to lower resolution

Source: Cloudflare Docs + Community Report

Why It Happens: Official docs state 1,600px hard limit for

format=avif

, but community reports indicate practical limit of 1200px for longest side as of late 2024. Note: Discrepancy between official docs (1600px) and reported behavior (1200px) needs verification.

Prevention:

typescript

// ✅ RECOMMENDED - Use format=auto instead of explicit avif
fetch(imageURL, {
  cf: {
    image: {
      width: 2000,
      format: 'auto' // Cloudflare chooses best format
    }
  }
});

// ⚠️ MAY FAIL - Explicit AVIF with large dimensions
fetch(imageURL, {
  cf: {
    image: {
      width: 2000,
      format: 'avif' // May fail if >1200px
    }
  }
});

// ✅ WORKAROUND - Use WebP for larger images
if (width > 1200) {
  format = 'webp'; // WebP supports larger dimensions
} else {
  format = 'avif'; // AVIF for smaller images
}

Issue #15: Image Cache by Device Type (Community-reported)

Error: Desktop and mobile see different cached versions, unexpected cache misses

Source: Cloudflare Community

Why It Happens: Images are cached by device type unexpectedly with no configuration option to disable this behavior in cache rules. Multiple users confirm this behavior as of Dec 2024.

Prevention:

Understand that purging cache requires purging for each device type
Use manual cache purging per device type via Cloudflare dashboard
Account for device-specific caching in cache invalidation strategies

Solution/Workaround: Manual cache purging per device type via Cloudflare dashboard when needed.

Issue #16: PNG Not Cached by Default

Error: PNG images not caching despite other image formats working

Source: Cloudflare Community

Why It Happens: Default file extensions cached by Cloudflare do NOT include

.png

. Default cached extensions:

.jpg

.jpeg

.gif

.webp

.bmp

.ico

.svg

.tif

.tiff

(PNG is missing).

Prevention: Create explicit cache rule for PNG files:

Dashboard → Caching → Cache Rules
Add rule:
```
URI Path
```
```
ends with
```
```
.png
```
→ Cache Everything

Advanced Topics

Custom Domains: Serve from your domain via

/cdn-cgi/imagedelivery/<HASH>/<ID>/<VARIANT>

(requires domain on Cloudflare, proxied). Use Transform Rules for custom paths.

Batch API: High-volume uploads via

batch.imagedelivery.net

with batch tokens (Dashboard → Images → Batch API)

Webhooks: Notifications for Direct Creator Upload (Dashboard → Notifications → Webhooks). Payload includes

imageId

status

metadata

Content Credentials (C2PA): Cloudflare Images preserves and signs image provenance chains. When transforming images with Content Credentials, Cloudflare automatically appends transformations to the manifest and cryptographically signs them using DigiCert certificates. Enable via Dashboard → Images → Transformations → Preserve Content Credentials. Note: Only works if source images already contain C2PA metadata (certain cameras, DALL-E, compatible editing software). Verify at contentcredentials.org/verify.

Browser Cache TTL: Default Browser Cache TTL is 2 days (172,800 seconds). Customizable from 1 hour to 1 year (account-level or per-variant). Important: Private images (signed URLs) do NOT respect TTL settings. Can cause issues when re-uploading images with same Custom ID - users may see old version for up to 2 days. Solution: Use unique image IDs (append timestamp/hash) or manually purge cache after re-upload.

Product Merge Migration (Nov 2023): Cloudflare merged Image Resizing into Images product with new pricing: $0.50 per 1,000 unique transformations monthly (billing once per 30 days per unique transformation). Migration Gotchas: Old Image Resizing bills based on uncached requests (unpredictable costs due to variable cache behavior). New billing is per "unique transformation" (image ID + params combination), not request count. Same transformation requested 1,000 times/month = billed once. Existing customers can continue using legacy version or migrate voluntarily.

R2 Integration for Cost Optimization: Cloudflare Images is built on R2 + Image Resizing. For cost savings, store original images in R2 and use Image Transformations on-demand:

Upload images to R2 bucket
Serve via custom domain with
```
/cdn-cgi/image/
```
transformations
No variants stored (transformations are ephemeral/cached)

Cost Comparison:

R2: 10GB storage + unlimited bandwidth (free tier)
Cloudflare Images: $5/month (100k images) + $1 per 100k transformations
R2 + Transformations: R2 storage + $0.50 per 1k unique transformations

Use Case: If you don't need named variants, batch uploads, or Direct Creator Upload features, R2 is more cost-effective.

Example Workers Pattern with R2:

typescript

export default {
  async fetch(request, env) {
    const url = new URL(request.url);
    const imageKey = url.pathname.replace('/images/', '');
    const originURL = `https://r2-bucket.example.com/${imageKey}`;

    return fetch(originURL, {
      cf: {
        image: {
          width: 800,
          quality: 85,
          format: 'auto'
        }
      }
    });
  }
};

Reference: Cloudflare Reference Architecture

Troubleshooting

Problem: Images not transforming

Symptoms:

/cdn-cgi/image/...

returns original image or 404

Solutions:

Enable transformations on zone: Dashboard → Images → Transformations → Enable for zone
Verify zone is proxied through Cloudflare (orange cloud)
Check source image is publicly accessible
Wait 5-10 minutes for settings to propagate

Problem: Direct upload returns CORS error

Symptoms:

Access-Control-Allow-Origin

error in browser console

Solutions:

Use
```
multipart/form-data
```
encoding (let browser set Content-Type)
Don't call
```
/direct_upload
```
from browser; call from backend
Name file field
```
file
```
(not
```
image
```
)
Remove manual Content-Type header

Problem: Worker transformations return 9403 loop error

Symptoms:

Cf-Resized: err=9403

in response headers

Solutions:

Don't fetch Worker's own URL (use external origin)
Don't transform already-resized images
Check URL routing logic to avoid loops

Problem: Signed URLs not working

Symptoms: 403 Forbidden when accessing signed URL

Solutions:

Verify image uploaded with
```
requireSignedURLs=true
```
Check signature generation (HMAC-SHA256)
Ensure expiry timestamp is in future
Verify signing key matches dashboard (Images → Keys)
Cannot use flexible variants with signed URLs (use named variants)

Problem: Images uploaded but not appearing

Symptoms: Upload returns 200 OK but image not in dashboard

Solutions:

Check for
```
draft: true
```
in response (Direct Creator Upload)
Wait for upload to complete (check via GET
```
/images/v1/{id}
```
)
Verify account ID matches
Check for upload errors in webhooks

Problem: Re-uploaded image still shows old version

Symptoms: Even users who never visited page see old image after re-upload

Solutions:

Use unique image IDs for each upload:
```
const imageId = \
```
${baseId}-${Date.now()}`;`
Set shorter Cache-Control headers (e.g., max-age=86400 for 1 day instead of 30 days)
Manual purge via dashboard after re-upload with same ID
Understand default Browser Cache TTL is 2 days - users may see cached version

Root Cause: Cloudflare respects origin Cache-Control headers. If origin sets long max-age (e.g., 30 days), images remain cached even after re-upload with same ID.

Problem: PNG images not caching

Symptoms: PNG images bypass cache while other formats (JPEG, WebP) cache correctly

Solutions:

Create explicit cache rule: Dashboard → Caching → Cache Rules
Add rule:
```
URI Path
```
```
ends with
```
```
.png
```
→ Cache Everything
Default cached extensions don't include
```
.png
```
(only
```
.jpg
```
,
```
.jpeg
```
,
```
.gif
```
,
```
.webp
```
,
```
.bmp
```
,
```
.ico
```
,
```
.svg
```
,
```
.tif
```
,
```
.tiff
```
)
